Borochlorate phosphors have shown their worth in modern day lighting over the last few years. Colour tunability of the phosphor is a modern techniques used to obtain white‐light‐emitting diodes (WLEDs). In the proposed work, Sm3+,Eu2+‐activated/co‐activated Ba2AlB4O7Cl phosphors were investigated for WLED applications as well as display devices. A convectional solid‐state diffusion method was used to synthesize the proposed phosphors. X‐ray diffraction (XRD) of the proposed phosphors confirmed the crystalline nature of the sample. Morphological studies on the samples were carried out using scanning electron microscopy analysis. A photoluminescence study of the colour tunable phosphor showed the characteristic peak of Sm3+ together with one broad peak for Eu2+ ions. Red to blue colour tunability was observed in the proposed phosphor with enhancement of Eu2+ ions. All these results showed the worth of this sample in WLED applications as well as in display devices. [ABSTRACT FROM AUTHOR] |
